FORCE-PUMP.

' SPECIFICATION forming part of Letters Patent No. 373,367, datedNovember 15, 1887.

' Application led August 16, 1886. Serial No. 211,050. (No model.)

.enable others skilled in the art to which it appertains to make and usethe same.

My invention relates to force-pumps, and has for its object thesimplification of parts, whereby a great saving in cost of manufactureis attained, and also in the labor usually required to elevate waterfrom one level to another.

In the accompanying drawings, forming part of. this specification, thesame numerals and letters of reference indicate the /same orcorresponding'parts.

Figure 1 is a side elevation, partly in section, of the' upper portionof nay-improved pump. Fig. 2' is a sectional elevation of the lower orsubmerged portion of the pump. Fig. 3 is a top plan view of the followerand n plunger with aportion of the piston-rod, showard or pedestal 2,being'secured by suitable screw-bolts, 3 3, passing through flanges 4 4,formed at the base of the said pedestal. This pedestal may be of anydesired ornamental design, and has a crank or operating-leven', pivotedin the upper portion thereof bymeans of the fulcrum-pivot 6. Thisoperating-lever extends outwardly from each side of the pedestal, and toone end thereof one portion of an elliptical connecting-link, 7, issecured by means of the bolt 8', while the other end of the said link issecured by means of the bolt 9 to the piston-rod R.

Connected to or cast with one side of the pedestal 2 is an arm, 10,which projects outwardly from said pedestal, and through which .thepiston-rod R passes and is steadied inits movement. This pistou-rod R ispreferably made of tubing and extends down through the platform 1 intothe submerged portion of the pump, having a double-acting plunger, 11,

mounted on the lower portion thereof, which operates in a follower, 12,surrounding the same. The plunger 11 plays in an inclined walledopening, 13, which extends entirely through the follower 12.

Secured to the pistou-rod B above the follower 12, by lneans of apivot-pin, 14, is a` spider, 15, which acts as a stop or guard for thefollower. This plunger and follower operate in a chamber, A, whichisdivided into two compartments alternately formed by the motion of thesaid plunger. On each side of this chamber A are two receiving-chambers`B B, which are circular in form and bounded by walls 16 17, the walls 16forming divisional partitions between the chamber A and the saidreceiving-chambers B B, a passage-way, 18, being left between the bottomplate, C, of these chambers and` the lower ends of the wall 16, thusconnecting the receiving and vcentral or forcing chambers. This passageis closed by means of the valve18', opening in an upward direction. Theouter walls, 17 17, have apertures or short pipes 19, throughV which theWater is drawn or fed into the receiving-chambers B by the action of theplunger 11 in the chamber A. These receiving-chambers are cylindrical inform, as shown in Fig. 4, and.

their lower ends are let into the bottom plate, G, while on the topportion of these chambers a cap-plate, D, is placed, having suitableapertures, d d, at its central portion, on each side of the plunger R,for the passage of water into the discharge-pipes 20 20.

Immediately above the cap-plate D, surrounding the plunger-rod B, andhaving free play thereon, is a washer, 21, which acts as a valve coverat the top of the submerged cylinder.

The cap-plateD has projecting sides d,pro vided with internalscrew-threads adapted to receive the screw-threaded ends of thedischarge-pipes 20. The inner walls of the discharge-pi pes 20 are alsoengaged by the divisional screw-threaded plate D', which supports thegland 22 for the stuffing-box mounted at this point, said gland beingsecured to the plate D by set-screws 23 23. Y

The discharge-tubes 20 extend upwardly through the platform 1, to whichthey are secured by means of bolts 2l 24, and are provided ICO withsuitable caps, 25 25, which are screwed thereon. The connecting-pipe 26unites the two discharge-pipes 20 20, the said connectingpipe having anoutflow-pipe, 27, engaging therewith, which extends above the platform 1a suitable distance for discharge. The plunger-rod R surrounds orstraddles the connecting-pipe 26, and thence passes through the platform1, as heretofore described, a space being left between the connectingpipe and the platform.

The operation of the pump is as follows: The lower cylinder, composed ofthe several compartments described, having been submerged and theplunger-rod operated to move the plunger down in the chamber A, thewater which has entered the chamber A through the valve 1S from theapertures 19 in the receiving-chambers B is forced up between the saidplunger' 11 and its follower 12, through the spider l5, and into thechamber formed above said depressed parts. XVhen the plunger-rod R isdrawn upward,the water is forced through the apertures d d in thecap-plate D into the discharge-pipes 20, through the connectingpipe 26,and into and out of the outflow-pipe 27, where it may be received in asuitable receptacle or conveyed and deposited as desired. rlhe operationbeing repeated the iiow becomes continuous and steady.v

It is obvious that manyminor details in the construction and arrangementof the parts could be made and substituted for those shown and describedwithout in the least departing from the nature and principle of myinvention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A force-pump comprising an upper section provided with the platform 1,the standard 2, the lever 5, the piston-rod R, the dischargepipes 20 and27, the plate D', the gland 22 and suitable connections to said gland,the capplate D, having an upwardly-opening valve, 21, and the lowersection provided with the central chamber, A, the lateralreceivingchambers B B, having apertures 19 19, the bottom plate havingthe connecting-passages 18 18 andthe valve 1S', and the piston havingthe conical plunger 11, the follower' 12, and

the spider 15, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.l
